i j SASI-I AISING AND LOWERING DEVICE.

Application filed August 10, 1922. Serial No. 580,894.

i To all 'whom it may concern:

j Be it known that I, NIOHOLAs C. LEIDGEN, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Sash Raising and Lowering Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a sash raising and lowering device' and has special reference to a mechanism which may be readily mounted in the door frame or body walls of an automobile for regulating a sash in the door or automobile body, and after the mechanism is understood, it will be apparent that the same can be generally used for raising and lowering members relative to a well or comparatively small compartments in which the members are housed when in lowered positions.l i

`One of the objects of my invention is to provide a raising and lowering device embodying a reciprocable member having power imparted thereto from a rotary manually operated shaft, and these elements may be easily mounted in the well of a door frame for shifting a sash in and out of the well, the sash having a traveler engaging the reciprocable'member which is adapted to raise and' lower the sash in suitable guides provided therefor inthe well of the door frame. E

Another object of this invention is to provide a reciprocable mechanism for raising and'lowering a windowsash, said mechanism including a reciprocable member movable in a vertical plane and actuated by an operating member shiftable in a horizontal or 'lateral plane.

A further objectof this "invention is to provide a sash raising' and lowering device embodying telescopic screw members and novel pieces of hardware `which insure a safe and positive adjustment of the sash without any danger of the sash accidentally lowering because of its weight, and vibra tions to which it may be subjected, particularly during the operation of an automobile equipped with sash adjusting devices `in accordance with my invention.

The above are a' few of the objects attained by the construction to be hereinafter described, and reference will now be had to the drawings, wherein- FigureA l is view -in elevation of the inner side of an automobile door frame having a sash and a device for raising and lowering the sash;

Fig. 2 is a vertical sectional view of the same;

Fig. 3 is an enlarged horizontal sectional view of the door frame, sash and raising and lowering device;

f Figa 4 is an enlarged horizontal sectional view of the device;

Fig. 5 is an enlarged vertical sectional ligfiew of a portion ofthe reciprocable mem- Fig. 6 is an enlarged vertical sectional view of a portion of the device, illustrating a Areciprocable operating member;

Fig. 7 is a horizontal sectional view'of a door frame having asash and a device opera'ltable by a reciprocable operating member, anc

Fig. 8 is an enlarged side elevation of another form of sash lraising and lowering lcglevice embodying telescopic screw memers.

In the drawing, the reference numeral l denotes,byV the way of an example, an automobile door frame having a lower outside panel 2, a sill 3, a-well t, channel guides 5, a sash 6, and a sill frame 7, said sill frame being ordinarily closed by an inside lower stationary panel, which has not been illustrated for the sake of clearance in showing the sash regulating mechanism. The above recited elements are of a conventional form at present used in the automobile industry, and reference will now be had to my mechanism located within the well 4L for raising and lowering the sash 6 in the channel guides 5.

The mechanism includes a vertical support having its lower end attached to the bottom of the frame l and its upper end attached to the sill frame 7. Adjacent the lower end of the support 8 is an angle bracket or bearing 9 for a rotatable shaft l0, said shaft being rectangular in cross section, except for its ends, so as to establish rotative continuity between said shaft and a yreciprocable member ll lslidable on said shaft, said member having its outer wall provided with diamond threads or grooves 12.

` The upper end of the shaft 10 has a bushing 13 journaled in a bearing 14 carried by the support 8, and on the upper end of the shaft is a beveled gear wheel l5 i is revolved. kEngaging the opposite 'side of the reciprocable member 11 is a traveler nut 2O having apertured lugs 21 s lidable 'on guide rods 22suported by the bearings 9 and 14 at the sides of the reciprocable member 1l. On the traveler nut 20 is stud 23 and rotatable on said stud is a hollow `roller 24 which has its open. endnprovided with a peripheral flange 25, said roller extending vinto a slot 26 in the depending` arm 27 of a channel binder strip 28 on the lower edge of the sash wlllncircling the stud 23 Vwithin ythe hollow flange roller 24 is a coiled eX- ansion s rino Q9 and the ex `ansive force P s ofuthis spring holds the flanged end of the roller 24 normally vagainst the arm 27 and the edges of the sash 6 normally against the channel guides 5, thus preventing rattling of the sash andthe pieces of hardware articulated therewith. .v A

When the shaft 10 is rotated and a reciprocable movement vimparted vto the member 11 the traveler nut Q0 will be 'caused to reciprocate faster than the member 11k and the sash 6 may be raised and lowered depending on'the `direction in which the shaft I1Q isY rotated by the rotary operating sha-tt 1 7. Instead of using this rotary operating shaft, I may userthe mechanism shown in Figs. 6 and 7. Mounted on the upper end of the shaft 10 is a pinion 30 meshing with a reciprocable rack 31 guided in al slotted "fra-me 32 'mounted' yon the inner wall of' the sill member 7 at a longitudinal slot 33 providing clearance for a handle 34 attached to the rack 31. By shifting the handle 34 movement may be imparted to the shaft 10 in a desired direction. y n

Reference will now be had to 'the other formof operating mechanism shown in Fig. 8. ,'Ihe support 8 lin this instance has a short shaft 10 journaled in the upper end ofthe support and in lthe upper end of a spiral screw member 35 lixed in or on the angle bracket or bearing 9 of the support 8. In

threaded 'engagement `with the stationary screw member 35 is a nut 36 mounted in the lower end 'of a tubular telescopic'spir-al lscrew member 37 slidable on the shaft 1'0 and adapted to rotate therewith. In screwthreaded engagement with the telescopic screw member 37 is a nut 38-having a stud 39 supporting the fsash 6 as previously descrew member 35 and the nut 38 to travel on i the screw member 37.

From the foregoing it will be observed that the sash shifting mechanism is carried by `a single support that may be easily mounted in the well 4 for raising or lowering the sash 6, and the nature ofthe mechanisin precludes accidental shifting of the sash because of its weight or vibrations to which the mechanism may be subjected during theoperation of a vehicle.

l[It is thought that the utility and operation of the two forms of my devicey will be upparent wit-hout further description, and while in the drawings there are illustrated thepreferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such changes, in size. shape and manner of assembling. as fall within lthe scopeol the appended claims.

IVhat I claim is 1. Means for raising and lowering a sash comprising a suport, a rotar shaft carried by said support and adapter to have rotation norma ly imparted thereto, a `reciprocable member on said shaft, a stationary nut carried b said support and engaging said reciprocle member to cause it to reciprocate during rotation of said shaft, and a traveler nut engaging sai reciproc'able member and adapted to raise or lower the sash, said traveler nut being guided adjacent said support. l

2. Means for raising and lowering a sash, as called for in claim 1, wherein the relation of saidreciprocable member and said travel nut is such` lthat said traveler is caused to travel faster than said reciprocable member.

3. Means for raising and lowering a sash, as called for in claim 1, and a spri presse sash engaging roller carried by sai traveler nut and adapted to prevent rattling of the sash. i

4. Sash raising and lowering means coinprising aureciprocable member, rotary means axially of said reciprocable member `fior imparting movement thereto, a Vtraveler' nut engaging said reciprocable member andthe sash, and means engaginglsai'd reciprocable Y adapted to shift the sash, aV reciprocable member enga-ging said -nut to impart movement thereto, and means engaging said reoiprocable member for reciprocating said member.

7. Sash raising and lowering means as called for in claim 6, wherein'the last mentioned means includes a stationary nut and a rotary shaft.

8. Sash raising and lowering means as called for in claim 6, wherein the last men- 10 tioned means includes a manually driven shaft axially of said reoiprocable member, and a nut engaging the outer wall of said reeiprooable member.

ln testimony whereof I affix my signature in presence of two witnesses.
